BACKGROUND: Lateral medullary infarction (LMI) is not an uncommon disease. Although lesions are usually restricted to the lateral medullary area, some patients have additional infarcts in other parts of the brain. The clinical features and prognosis of isolated LMI (pure LMI, LMIpr) have been investigated. However, it remains unclear whether clinical characteristics, prognosis and factors associated with prognosis differ between patients with LMIpr and those with additional lesions (LMI plus, LMIpl)...

Adult vascular smooth muscle cells (VSMCs) possess the peculiar ability to de-differentiate in response to extracellular cues, such as vascular damage and inflammation. De-differentiated VSMCs are proliferative, migratory, and have decreased contractile capacity. VSMC dedifferentiation contributes not only to vascular repair, but also to cardiovascular pathologies, such as intimal hyperplasia/restenosis in coronary artery or peripheral vascular diseases and arterial aneurysm. We here demonstrate the role of ubiquitin-like, containing PHD and RING finger domains, 1 (UHRF1) as an epigenetic master regulator of VSMC plasticity...

Polyarteritis nodosa is a systemic necrotizing vasculitis which predominantly affects medium-sized arteries. It is a rare disease nowadays. Both the nomenclature and the classification of polyarteritis nodosa was amended several times in the past. Currently, there is a distinction between the primary form described as classical polyarteritis nodosa and other forms that are associated with their probable cause e.g. with viral hepatitis B, C or HIV infection. Moreover, polyarteritis-like necrotizing vasculitis can appear in the course of genetic diseases caused by mutations in single genes...

Atherosclerosis is an inflammatory disease of arterial walls and the rupturing of atherosclerotic plaques is a major cause of heart attack and stroke. Imaging techniques that can enable the detection of atherosclerosis plaques before clinical manifestation are urgently needed. Magnetic resonance imaging (MRI) is a powerful technique to image the morphology of atherosclerotic plaques. In order to better analyze molecular processes in plaques, contrast agents that can selectively bind to plaque receptors will prove invaluable...

BACKGROUND: The OLR1 gene has been identified as a candidate gene for coronary artery disease (CAD). Six single-nucleotide polymorphisms (SNPs) of the OLR1 gene located within intron 4 (IVS4-27G>C, IVS4-73C>T, IVS4-14A>G), intron 5 (IVS5-70A>G, IVS5-27G>T) and 3'UTR (188C>T) comprise a linkage disequilibrium (LD) block, which is strongly associated with the elevated risk of CAD. OBJECTIVES: We aimed to investigate the effects of the OLR1 IVS4-14A>G and -73C>T SNPs on metabolic parameters in Turkish CAD patients, and the linkage between these 2 genetic variants...

The vascular endothelial growth factor (VEGF) family of peptides and caveolins (CAVs) are reported to contribute, in early graft failure in patients, a coronary artery bypass grafting (CABG). To investigate the possible association of ultimate luminal occlusion to VEGFs and CAVs expression, a functional analysis (based on the molecular biology, bioinformatics, histology, and clinical studies) was performed. Twenty-four hundred and sixty-eight CABG patients diagnosed with multivessel stable coronary artery disease (CAD) were enrolled into prospective study and assigned to two subgroups: double- and triple-vessel CAD subjects...

Background In patients with stable coronary artery disease, aspirin, a statin, and an angiotensin-converting enzyme inhibitor are recommended as first-line agents for secondary prevention. Subgroup analyses of the previously published Hungarian Perindopril plus Amlodipine in PAtients with Coronary Artery Disease (PAPA-CAD) non-interventional trial demonstrated that the addition of the metabolically beneficial, fixed combination of perindopril + amlodipine to atorvastatin further improves the patient's lipid profile...

Vascular diseases refer to medical conditions that narrow blood vessels. Narrowed cardiac or cerebral arteries can lead to myocardial infarction or ischemic stroke. Risk factors including atherosclerosis, hypertension, and diabetes may induce either cardiovascular or cerebral complications. Based on current research, garlic favorably affects atherosclerosis, hypertension and diabetes, and helps decrease the risk of myocardial infarction and ischemic stroke. Garlic has been utilized for hundreds of years as a natural health remedy...

The presence of myocardial ischemia is the most important prognostic factor in patients with coronary artery disease, and ischemia-directed revascularization has been a standard of care. Fractional flow reserve (FFR) is an invasive method used to detect the functionally significant epicardial coronary stenosis, and FFR-guided revascularization strategy has been proven to be superior to angiography-guided strategy. Recently, a hyperemia-free index, instantaneous wave free ratio (iFR), was developed and showed its non-inferiority for clinical outcomes compared with FFR-guided strategy...

Quantification of myocardial flow reserve (MFR) provides diagnostic value for detection of cardiovascular artery disease. However, the common calculation method for MFR requires dynamic acquisition and specific software. The study aimed to predict coronary artery disease by simpler calculation of myocardial count without the use of dynamic data from13 N-ammonia myocardial perfusion positron emission tomography (MP-PET). This study included 40 consecutive patients suspected of ischemic heart disease and 7 healthy controls (34 men and 13 women, 66 ± 12 years)...
